Hi,
I have a Sony Vaio laptop, VPCEE2S1E. It came with 4gb (2 x 2gb) RAM, all of which was recognised and all of which was usable. I upgraded it with 8gb (2 x 4gb) of compatible memory, however both the BIOS and Windows still think that I have 4gb, again all of which is usable.
There is no option to alter memory mapping in the BIOS (Insyde H2O), the BIOS is the latest version and maximum memory is unchecked in msconfig.
Anyone any idea what I'm doing wrong?

Possibly one of the new sticks is bad? Try it with just one, then the other.

sounds like one of the sticks of ram is bad. take one out and see what happens. if it works... swap the sticks and see if the other one works or not. lets start with that.

Might clean the DRAM contacts and blow out the sockets, may have lint or other debris in their.
